lb all whom. it may concern:

Be it known that I, EDWIN J. NEWTON, a citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Rod-Packing, of which the following is a specification.

My invention relates to that class of engines wherein the crank-case is used as a compression-chamber, and has for its object to prevent the escape of the fluid-pressure from the interior of the case when the pressure is raised and to accomplish this result in a manner which will not only be inexpensive, but will reduce the friction to a minimum. My method of accomplishing this result may be more readily understood by having reference to the accompanying drawings, which are a part of this specification and are hereunto annexed, in which I Figure l is a view of a part of a crank-case, showing my improved device applied to the crank. Fig. 2 is an end view of the same. Fig. 3 shows a modified form of my invention. Fig. 4 is an end view of the same. Fig. 5 is a detail view.

Similar figures refer to similar parts throughout the entire description.

In the drawings, 1 is the wall of the crank case.

2 is a crank-bearing.

3isthe crank, whichis formed with ashoulder L, fitting to and coinciding with a recess 5, formed or turned in the inner wall of the hearing 2, although it may be found desirable in practice to make this shoulder 4: of a separate ring instead of having it integral with the crank, in which event it may be secured to the crank by means of any of the usual methods employed in such cases. The inner face of the shoulder or ring 4: has a recess which is turned thereon, the corner? and the corresponding corner 8 on the recess being cut away, so as to form a V-shaped recess 9. A washer 10 is cut from some flexible material, preferably rawhide, its inner edge 11 extend ing almost to the crank 3. This rawhide Washer 10 is secured in place by means of screws 12, which are threaded into the bearing 2, a metal ring 13 being provided to insure a firm hold upon the rawhide washer.

The action of the device is as follows: hen the pressure is raised, it presses against the inner face of the rawhide washer in the direction indicated by the arrows. The result is the washer is depressed and fills the recesses 6 and 9, it being obvious that the higher the pressure is raised the tighter this washer, which acts as a valve, will seat itself. At the same time the fact that it is constructed of a iiexible material permits the crank to move laterally in the bearing without permitting any leakage of the pressure.

Another or modified form of my invention is shown in Figs. 3 and 4, in which a metal ring 1a is shown surrounding the shoulder 4, one of its faces 15 bearing against the inner wall of the crank-case. This ring turns with the crank, butis movable laterally thereon. Coilsprings 16 are placed at suitable intervals and exert a tension which holds the face 15 of the ring 14@ against the inner wall of the crankcase, insuring a tight joint at this point; but there is a decided tendency to leakage through the joint between the crank or shoulder thereon and the inner surface of the ring 14, due to the fact that it has to be constructed with sufficient looseness in order to permit of the lateral movement of the crank. This is overcome by means of the rawhide washer 10, which is fitted and arranged to be held against the ring 14: and the shoulder or crank, it being obvious that the higher the pressure is raised in the crank the tighter this washer will seat itself in the recess 9, formed between the shoulder 4 and the ring 14:.

Other modilications may suggest themselves to persons skilled in the art by which my invention may be adapted to various styles of engines which will notdeviate essentially from my invention, the essential feature of which is the providing of a washer of flexible material to close the opening between the crank and the bearing which shall be seated by the pressure in the crank-case.

Having described my invention, what I regard as new, and desire to secure by Letters Patent, is-

1. In a gas-engine, the combination of a crank-case witha crank journaled in a bearing in the wall of said crank-case, said crank having a shoulder formed thereon fitted to and coinciding with a recess in the inner face of said bearing, a V-shaped recess formed at the junction of the said shoulder and the said recess, a washer of flexible material covering said V-shaped recess, means to secure and hold said washer in position, for the purpose set forth substantially as described.

2.
